IMPROVEM E NT IN CULTIVATORS.

Specification forming part of Letters Patent No. 43,901, dated August 23,'1864.

panying drawings and the letters of reference' marked thereon. A

The nature of my invention consists in so constructing a enltivator that by a simple adjustment of the plows the soil can be thrown either to or from the plant, and also the depth whichV the plows run in the soil can be readily gaged. The space between the two sets ot'plows-whieh run, when in use, one on each side of arow--can be varied to adapt it to the different widths of space between the rows, and the plows can be thrown entirely from the soil to be driven to and from-.the held.

To enable others skilled in the art to make and use my invention,I will proceed to describe its construction and operation.

Figure l represents a top view of my improved cultlvator; Fig. 2, a sidevew otl the same. Fig. 3 is a side view of the cross-piece A.

T, the tongue ot" the cultivator, is irmly attached to the front cross-piece, B, and extends back to support the vibrating lever G. The two uprights F are supported upon wheels, and are attached to B by means of strips of metal,which are fastened to the sides of F and extend up through the slotsin B and the plates e c, and are tightened by means ot' screw-nuts, as shown in Fig. 1.

To the uprights FF the plow-beams E E are attached by means of clevises,'as shown at a a, and they can be moved up or down on the uprights to regulate the depth of the plows in the soil. Fastened rmly to each of these beams is the plow-standard S, as more plainly shown in Fig. 2, the tops of' which are fastened to the cross-piece A, and for th'e purpose of strength the braces d d are used, extending from the plow-beams to the cross-piece A. 'Ihey are all fastened to the cross-piece A by means o t' bolts and nuts, or in some way so that they can be readily loosened for removal.

Z is a lever, with one end attached to the plow-beam Ill in such a manner as to allow it to turn vertically. Near the center of said lever the rod r is attached, which vis also hooked to one end of the vibrating lever C. To the other end ot O the rod r is hooked, which connects with the other plow-beam E. The connectingpiece D is bent both vertically, as shown in Fig. 2, and has two lateral angles of about fortyve degrees each, as shown in Fig. 4, which gives a convenient shape to be attached to the plow-standard S, and gives both plowblades the same relative angles to the direction ofthe line ot draft, and places the rear blade so that it commences to cut the soil just where thefrontbladeleavesituncut. Theplow-blades also have the same relative positions to each other and the same angles to the line of draft when the two sides ofthe eultivator arechanged places, so as to throw the soil from the row instead ot to it.

lo regulate the depth of the plows in the soil,

the attachments ot' the plow-beams E E to the standards F F are raised or lowered inL the holes shown in Fig. 2. To throwthe soil from the row, instead ot' to it, the clevises a a are unfastened, the rods r r' unhooked, the nuts y y y y loosened, and the two sides ot' thevcultivator simply changed places. To regulate the width of space between the plows to adapt them to the space between the rows, the nuts Having thus fully described the construction i and operation of my improved cultivator, what I claim as my invention, and desire to secure by Letters Patent, is e The combination and arrangement ofthe lever 'Z, the rod r, the vibrating lever O, the

rod r', and the plow-beam E, when constructed and operating substantially as herein delineated and described.
